Abstract

é descrito um evacuador para fornecer vácuo a um dispositivo em um sistema de ar de um motor com impulsionamento reforçado. o evacuador define um corpo que compreende uma seção motriz convergente, uma seção de descarga divergente, pelo menos uma porta de aspiração e uma abertura de venturi localizada entre uma extremidade de saída da seção motriz convergente e uma extremidade de entrada da seção de descarga divergente. uma distância linear é medida entre a extremidade de saída e a extremidade de entrada. a distância linear é diminuída em seu comprimento se for necessário um vácuo de aspiração maior, em um conjunto específico de condições de operação, e as distâncias lineares são aumentadas em seu comprimento se for necessária uma taxa de fluxo de aspiração mais elevada no conjunto específico de condições de operação.
